I have had Fentanyl
once and it was IV while at the hospital when they were prepping me to see if I had stomach cancer (which was negitave phew) and they added versed as well. how much they used I am not sure all I know is they did labs too threw my IV and I have SEVERE Phobia of needles. I can look at a hepron lock and be ok just dont ask me to be corperative for blood/lab work. Anywho it put me in to damn near shock so they upped both the fentanyl and versed...after and hour still looking like I am suffering from a small seizure from the panic attack
. So they call anasthisologist and drop me with profronol now this is the interesting part. Hardest opiate
I had taken prior was 2mg Diluaded and Oxycodone
. 30mins later I was awake from the procedure but I don't know if it was the fentanyl or the versed or both but I was just gone for 18 or so hours. My body is just odd like that. Opiates
take a while to kick in but when they do...they last. As for mainlining it unless you know EXACTLY how much you have, its not street shit and an actually RX Ampule and some one to watch you in case you go over that VERY little line of sleep/dead I would HIGHLY NOT RECOMMEND IT. Fentanyl is not a drug
to really dink around with. It is less euphoric when compared to Morphine
but is 50-100X more strong. Great painkiller not really best to get "Fucked up on" recreational.
